A method of making a smoking article comprising a rod of smokeable material and a tubular support in which the rod is slidably received, comprising:
- winding a blank of sheet material in a spiral to form the tubular support, such that the tubular support is configured to slidably receive a rod of smokeable material such that the received rod is slidable in the tubular support between a retracted position and an extended, operative position.
Machinery for manufacturing smoking article components, including:
